hcg problems

I think I was mistakenly put on testosterone by my endo and am now taking HCG and am not sure if it will help my fatigue and fogginess. my LH went to 0 the endo said that was ok and my body stopped producing testosterone and I had a fatigue crash.
now maybe I need to look at HCG or not to restore my energy from testosterone. is the safe dose 500IU a week?
